I do not understand relations 😟 (many to many, users can follow and have followers)

export const usersTable = sqliteTable('users', {
id: text('id').primaryKey(),
username: text('username'),
})

export const usersRelations = relations(usersTable, ({ many }) => ({
questions: many(questionsTable),
followers: many(usersTable, { relationName: 'followers' }),
following: many(usersTable, { relationName: 'following' }),
}))

export const usersToUsersTable = sqliteTable('users_to_users', {
followedId: text('followed_id')
.notNull()
.references(() => usersTable.id),
followerId: text('follower_id')
.notNull()
.references(() => usersTable.id),
})

export const usersToUsersRelations = relations(usersToUsersTable, ({ one }) => ({
followed: one(usersTable, {
fields: [usersToUsersTable.followedId],
references: [usersTable.id],
relationName: 'followers',
}),
follower: one(usersTable, {
fields: [usersToUsersTable.followerId],
references: [usersTable.id],
relationName: 'following',
}),
}))
export const usersTable = sqliteTable('users', {
id: text('id').primaryKey(),
username: text('username'),
})

export const usersRelations = relations(usersTable, ({ many }) => ({
questions: many(questionsTable),
followers: many(usersTable, { relationName: 'followers' }),
following: many(usersTable, { relationName: 'following' }),
}))

export const usersToUsersTable = sqliteTable('users_to_users', {
followedId: text('followed_id')
.notNull()
.references(() => usersTable.id),
followerId: text('follower_id')
.notNull()
.references(() => usersTable.id),
})

export const usersToUsersRelations = relations(usersToUsersTable, ({ one }) => ({
followed: one(usersTable, {
fields: [usersToUsersTable.followedId],
references: [usersTable.id],
relationName: 'followers',
}),
follower: one(usersTable, {
fields: [usersToUsersTable.followerId],
references: [usersTable.id],
relationName: 'following',
}),
}))
this is the code I tried but I messed up the relations and the error says the following:
throw new Error(
^

I realize that I need a separate table follows to store a follower (from) id and following (to) user id... but I do not understand how to solve this error
